SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 619,232, dated February7, 1899. Application filed A ril 11 1898. Serial No. 677,129. llomodel.)

To all whom it may concern:

Beit known that I, OTTO W. SOHAUM, a citizen of the United States,residing in Phila delphia, county of Philadelphia, and State ofPennsylvania, have invented certain new and useful Improvements inShuttles; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

The object of my present invention is to provide a shuttle forswivel-shuttle or ribbon looms with an increased bearing surface andalso to provide a shuttle-block for said shuttle having a race-wayconforming in shape to the increased bearing-surface of said shuttle,whereby the further dropping or depressing of the nose of the shuttle isprevented and besides insuring a more perfect working of said shuttleincreases its durability and also the durability of the shuttle-block. Afurther object is to provide a shuttle with a runner having its grain inthe direction of the edges of the runner and its nose constructed of aseparate piece of wood and secured to said runner.

The invention consists in the improved shuttle, its shuttle-block, andin the combination and arrangement of the various parts, substantiallyas will be hereinafter more fully described, andfinally embodied in theclauses of the claim.

In the accompanying drawings, Figure 1 is a top plan view of my improvedshuttle; Fig. 2, an underneath view of Fig. 1; Figs. 3 and 4, rearelevations of the shuttle; Fig. 5, an enlarged sectional view on theline :1: a: of Fig. 1; and Fig. 6, a view similar to Fig. 5 andillustrating the shuttle in the raceway of my improved shuttle-block,the latter being shown in section and partly broken away.

The shuttle which is illustrated in the drawings is intended for aribbon-shuttle, and consists of the runner a and the nose I), which areglued or otherwise secured together, as at c. The runner is provided inits under side with a toothed rack d of ordinary construction and at itsouter lower portion with an elongated flange or projection e,rectangular in cross-section, as clearly illustrated in Figs. 5 and 6 ofthe drawings.

The upper portion of the runner a is provided at or near its inner edgewith an elongated rectangular groove f, While the remaining top portionis flattened, as at g, and at right angles to the back h of the runner.

The shuttle-block 71 contains the shuttlerace m, the top at of which isadapted to be engaged by the bearing-surface g of the runner, While thedownwardly-extending projection 0 of the shuttle-block'i conforms inshape to and is adapted to engage the rectan gular channel or groove fin said runner.

The lower portion of the shuttle-race conforms in shape to the lowerportion of the runner and can be of any suitable design or construction.

From the foregoing it can be seen that the runner of the shuttlefurnishes an increased bearing-surface with the top portion of theshuttle-race, as its flattened portion 9 is in engagement with theflattened portion n in said block, by which arrangement the dropping ofthe shuttle-nose is prevented, which is of the greatestimportance duringthe process of weaving, as will be manifest to those familiar with theart. It will also be seen that owing to the fact that the runner isspaced from the rear wall of the race the contact between the runner andthe walls of the race is minimized and confined only to points wheresuch contact is necessary in accordance with the principles of myinvention.

As heretofore stated, the shuttle is constructed of two piecesthat is tosay, of the runner a and of the nose bwhich are glued or otherwisesecured together, the nose being straight and the runner having beenpreviously bent to the proper circle from a piece of straight-grainedwood. The nose or front portion of the shuttle may also be ofstraightgrained wood, and thus furnishes, together with its runner, ashuttle which is very durable and strong, (as there is no cross grain toit,) especially on the points, which are apt to chip off.

I do not intend to limit myself to the precise construction shown anddescribed, as various alterations can be made without changing the scopeof my invention; but

What I claim as new, and desire to secure by Letters Patent, is

'1. A shuttle consisting of a substantially straight shuttle-nose havingits grain running straight and longitudinally thereof, and a curvedrunner secured to said nose and having its grain parallel to its curvethroughout its entire length, substantially as described. 2. A shuttleconsisting of a substantially straight sh uttle-nose having its grainrunning shuttle comprising a substantially straight nose having itsgrain running straight and longitudinally thereof and a curved runnersecured to said nose and having its grain parallel to its curvethroughout its entire length, said runner having a fiat widened upperbearing-surface extending from its free edge inwardly toward the nose,and arranged to impinge squarely against said wall, and said runnerbeing formed to closely fit between the upper and lower walls of therace adjacent its line of connection with the nose and spaced from therear wall of said race, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this6th day of April, 1898.
